What exactly is that OpenCL option in Capture One for? by Luke Cartledge

C!_OpenCL This is a question that I regularly get asked on and off shoots. To make things simpler I thought I should post a quick description of what it is, why the option is there and the difference it can make.


The option to automatically use OpenCL or not was introduced to Capture 6.0. In version 7.0 this was made slightly more complicated as the option is now available separately for image display and file processing.

To start with OpenCL stands for Open Computing Language and in terms of Capture used to allow programs to tap into the processing power of graphical processor unit (GPU) on the graphics card of your computer.

Current graphics cards are actually incredibly powerful processors on their own. The major manufacturers, AMD and Nvidia, have pushed the technology hard to be able to render very fast, detailed graphics for gamers. This has led to graphics processors with multiple cores and very high clock speeds (MHz/GHz) targeted at rendering detailed textures to screen quickly. This power goes unused most of the time as the computers main central processor unit (CPU) is normally used to process files in Capture One.


The theory is that with the Auto setting in Capture One, the software is able to access this extra processing power when it is rendering previews or processing out files to TIFF or JPEG formats.

The reality is that unless you are using an Apple computer with a recent graphics card and the operating system is at minimum Snow Leopard (10.6) or above, the technology is not supported.

As a general troubleshooting tip, if there is any doubt regarding the ability of your mac to support this feature, then turn it off. Also if Capture running slowly or at all jittery, I would recommend it as things to check and switch off.

If you want to go into further detail about Phase One's own advice on the subject, then go here. And for a detailed list of the Apple computers that will definitely not support this feature you can always check this page.

Adobe Creative Suite becomes Creative Cloud, goes subscription only by Luke Cartledge

adobe-CreativeCloud_Logo At the company's MAX conference, on Monday, Adobe announced the major change to it's Creative Suite of applications, from boxed or downloaded set to an online only model called Creative Cloud. From July the only way to purchase Photoshop and all the other applications in the suite will be via a monthly subscription model. This is a major from the past and comes with both good and bad points.

the change is that Adobe should be able to update applications on a more continual basis. This moves Adobe away from the traditional and allows Adobe to add improvements when they become available. Testing new features and technologies could become far quicker as Adobe will be able to receive live feedback and bug reports.


The Creative Cloud subscription service already has over half a million subscribers after an initial roll-out last year, together with Creative Suite 6. However the new service will come with some potentially very useful integrated features. Every individual subscriber will receive cloud storage that connects the traditional applications with apps like Photoshop Touch for the iPad and other devices. Full access to a Behance account is included which provides a simple platform to publish and share your work.

For Adobe the new model will also change the landscape regarding piracy. Photoshop has long been pirated pieces of software worldwide and with this change it will become much harder to do. I will make no

all this is that here in the UK we appear to be paying something of a premium again. Where as in US the monthly subscription runs to (£, on this side of the pond we will be paying £46.88/month. There has always been a disparity between the price of Adobe products in different worldwide territories. However originally the company justified this with things like taxes, customs duties and other marketing expenses. I fail to see, however, where the near 46% difference can come from when everything is delivered and supported in the cloud.

Online Lighting Diagram Tool by Luke Cartledge

OLDC_01Here is a useful tool that could really help plan, test and record your lighting setups. The Online Lighting Diagram Creator (OLDC) provides a simple interface in which you can relatively quick put together a plan view of a lighting setup that you have used or want to try. This would be great for photographers wanting to help their assistants to understand what they want and for assistants to record lighting setups that they have used and want to use again.

The interface provides lots of options and items for you to place around the work area. There is a good selection of lights and modifiers available for the smaller setups. However there is a glaring lack of tungsand some of the more modern flash kits, including Breise, are missing.

In general though this is a nice, free tool that could easily help photographers and assistants alike.

Adobe Photoshop Lightroom 5 now in Public Beta by Luke Cartledge

Adobe Labs has announced the public beta testing program is now open for version's ever-popular software Lightroom. This release comes with a list of very interesting new features that bring this software closer in post-processing functionality to Adobe's full Photoshop.

New Features in Lightroom

  • Advanced Healing Brush – Easily remove objects and fix defects—even those with irregular shapes such as threads or lint—with a single brush stroke. Take precise control over what's being removed as you make unwanted objects just disappear.
  • Upright – Straigha single click. Upright analyzes images and detects skewed horizontal or vertical lines. You choose methods, and Upright can even straighhorizon is hidden.
  • Radial Gradient – Lead your viewer's eye through your images with more flexibility and control. The radial gradient tool lets you create off-center vignette effects, or multiple vignette areas within a single image.
  • Offline editing with Smart Previews – Easily work with images without bringing your entire library with you. Just generate smaller stand-in files called Smart Previews. Make adjustments or metadata additions to Smart Previews and your changes will be automatically applied to the full-size originals later.
  • Video slideshow sharing – Easily share your work in elegant video slideshows. Combine still images, video clips, and music in creative HD videos that can be viewed on almost any computer or device.
  • Improved photo book creation – Create beautiful photo books from your images. Lightroom includes a variety of easy-to-use book templates, and now you can edit them to create a customized look. Upload your book for printing with just a few clicks.

The first of these features is definitely going to make workflows quicker as spot and defect cleaning is ofnow that images have to be round-tripped out to Photoshop for further work. This should save time and disk space as files can be kept in RAW inside the software.

The software can be downloaded here, and it should go without saying but this is still a beta testing phase so there may be some bugs. I would certainly not recommend using this as your main version of Lightroom. You will also need to log in with your Adobe ID to verify the download.

I will be testing this version out over the next few weeks and will write up my verdict on these updates.
